Papua puffer/toby

This small puffer fish is very similar to the Fiji spotted puffer. The blue spotted puffer has a brown body with electrical blue spots and a large black spot with a blue ring right below the dorsal fin. Like other pufferfish they gain propulsion with their dorsal and anal fin. This one was moving at high speed, as can be seen by the blurry background. Pufferfish feed on particles in the water column and also scrape algae and detritus off the substrate.
